TACAN AND VOR
PROCEDURES
A. Station passage indications
* Operational characteristics
1.
VOR
* Course intercepts and
tracking
a.
VOR bearing pointer will break lock in
* Approaches
the cone-of-confusion and disappear
from display
b.
CDI will also disappear
c.
The display system does not
incorporate a TO-FROM indicator, like
many other aircraft
d.
There are no NAV warning "flags"
e.
For timing purposes, station passage
is when the VOR bearing pointer
reappears following passage through
the cone-of-confusion
2.
TACAN
a.
Minimum DME - AGL altitude divided
by 6,000
b.
Point at which DME stops decreasing
NOTE: Due to the size of the TACAN
cone-of-confusion, it is possible to
pass over a TACAN station,
significantly to one side or the other
while transiting through the cone.
NOTE: When making course changes
over a station and DME is available,
the pilot is expected to begin a turn
before station passage so as to roll out
on the desired outbound course.
